3.4.2 Source ID (Address) S2
The AnyBus-S Modbus Plus module uses one source ID address from 1 -64 to configure what node it will extract the global data from, sent during the token pass. The amount of extracted data is set by the initialisation, which will be described later. The Source address is also configurable with the fieldbus specific mailbox messages, along with the GDB offset, please see chapter 5.
The address is set in binary format.
